\text{Then the diameter equals }9.938515
Then the diameter equals 9.938515
diameter is radius times 2
\text{Final Answer:}
Final Answer:
d\approx 9.9\text{ m}
d≈9.9 m
Round to nearest tenth
Answer:
independent, 1/4
Step-by-step explanation:
The events are independent because what occurs on the first flip does not affect the second flip
P(heads) = 1/2
P(heads, heads) = 1/2*1/2 = 1/4
Answer:
9/20
Step-by-step explanation:
.45 = 45/100
Divide the top and bottom by 5
45/5 = 9
100/5 = 20
The fraction becomes 9/20
Answer:
17 1/3
Step-by-step explanation:
10 + 6 + 1/2 + 5/6
Turn 1/2 into 3/3 =3/6
10 + 6 + 3/6 +5/6
10 +6 = 16
3/6 +5/6 = 8/6
Put 8/6 into mixed number than add it to 16
8/6= 1 2/6
Finally, add 1 2/6 and 16 it would equal 17 2/6 aka 17 1/3
